四、詞語辨析：

1. every 與 each 的區別：

every 用來表整體，each 用來表個別。each 最低需是兩，every 最低需是三。every adj.

every 作主用單數，each 可單也可復，作主、作定用單數，其他情況用復數。 each  adj./ pron.

every teacher knows her.

there are lots of trees on each side of the road.

each of the road has a dictionary.

2. on the earth  在地球上，作地點狀語，位于句首或句末。 on earth 究竟，到底。用于疑問句或副詞后，加強語氣。

all the living things on the earth depend on the sun. /  what on earth do you mean?

3. human, 指包括男人女人孩子的“人，人類”，有別于動物,自然景物，機器等的特殊群體，也可指具體的人。

person, 無性別之分，常用于數目不太大，而且數目比較精確的場合。

people, 泛指“人們”，表示復數概念。

man,前不帶冠詞而且單獨使用時，指“男人”，a man 可指“一個人/ 一個男人”，復數形式為men.

he was the only human on the island.

there are only three persons in the room.

there are many people there.

man is stronger than woman.

4. seem 連系動詞，好像，似乎，看來。有下面幾種用法：

seem to do sth. 似乎/看起來/好像做某事。  i seem to have left my book at home.

it seems/seemed that   看起來好像…, 似乎….    he was very happy.

seem to be + 形容詞/名詞 = seem + 形容詞/名詞。  she seems to be happy.= she seems happy.

5. probably ad. maybe 相當于 perhaps. 也許，大概，可能。作狀語.

probably 用于句中，可能性最大。 he will probably come tomorrow.

maybe/perhaps 用于句首。  maybe/perhaps you are right.

1.        during / for / in  介詞，在……期間。說到某事是在某一段時間之間發生的用during; 說到某事持續多久則用for; 說到某事具體發生的時間用in.

一般將來時結構：

肯定式： 主語 + will/shall + 動詞原形 + 其他          will 用于各種人稱，shall 用于第一人稱。

         主語 + be going to + 動詞原形 + 其他         be 隨人稱、數和時間的變化而變換。

否定式： 在will/shall/be 后面加 not.    will not = won’t .

一般疑問句： 將will/shall/be 提到主語前面。
